Jackson in December pleaded guilty to receiving child pornography and to possessing more than 1,000 such images.

Police say an individual contacted officers last August about child porn images on a cellphone that Jackson left in the person's car.

Jackson told police that he has a history of exploiting children. An officer testified that Jackson described how in 2007 a woman named Amber Schmidt "bought" him a 12-year-old girl for his birthday. Jackson says he molested the child.

Schmidt in January pleaded guilty to transporting and shipping child porn.
